During the production process of the molded case circuit breaker, the combination screw needs to be installed on the static contact and the connecting plate of the molded case circuit breaker. If the combination screw can be installed successfully, it is a good product; if the combination screw cannot be installed, it is a defective product. The staff will recycle the defective products in time to avoid the outflow of defective products to ensure the quality of the molded case circuit breaker.

[0088] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0089] This embodiment provides an automatic assembly device for molded case circuit breaker combination screws, which can realize automatic assembly of combination screws 500, has high assembly efficiency, and reduces the labor intensity of workers.

[0090] Specifically, if Figure 1-3 As shown, the automatic assembly device for molded case circuit breakers (MCCBs) includes a workbench 100, a conveyor line 200, a feeding mechanism 400, a locking mechanism 600, an assembly inspection mechanism 700, and a defective product transfer mechanism 800. The conveyor line 200, feeding mechanism 400, locking mechanism 600, assembly inspection mechanism 700, and defective product transfer mechanism 800 are all mounted on the workbench 100. The conveyor line 200 is used to transport the molded case circuit breakers 300 to be assembled to the assembly station and then transport the assembled MCCBs 300 to the next process. The feeding mechanism 400 is used to transport the assembly screws 500 to the loading station. The locking mechanism 600 removes the assembly screws 500 from the loading station and installs them into the threaded holes 310 of the MCCB 300 according to a set torque, completing the automatic assembly of the assembly screws 500. Compared to the manual assembly method in the prior art, this method reduces labor intensity and improves assembly efficiency. The assembly detection mechanism 700 is used to detect whether the assembled molded case circuit breaker 300 is qualified. If qualified, it indicates that the molded case circuit breaker 300 is a good product, and if unqualified, it indicates that the molded case circuit breaker 300 is a defective product. By setting up the assembly detection mechanism 700, it can help staff to identify defective products and prevent defective products from flowing to the next station, which is beneficial to improving the qualified rate of the molded case circuit breaker 300. The defective product transfer mechanism 800 is used to move the defective products detected by the assembly detection mechanism 700 to the defective product station 810. By setting up the defective product transfer mechanism 800, it is possible to automatically eliminate defective products without manual participation, with a high degree of automation, which reduces the labor intensity of the staff. In this embodiment, if Figure 2 and Figure 3 As shown, the threaded holes 310 are provided on two opposite sides of the molded case circuit breaker 300 , and three threaded holes 310 are provided on each side, and the threaded holes 310 on the two opposite sides are provided in a one-to-one correspondence.

[0091] Furthermore, if Figure 4As shown, the locking mechanism 600 includes a first bracket 610 and a first locking assembly 620. The first bracket 610 is disposed on the workbench 100. The first locking assembly 620 is disposed on the first bracket 610. The loading position includes a first loading position. The first locking assembly 620 is capable of attracting the assembly screw 500 at the first loading position and assembling it into the corresponding threaded hole 310. In this embodiment, since threaded holes 310 are provided on opposite sides of the molded case circuit breaker 300, the locking mechanism 600 also includes a second locking assembly 630. The first locking assembly 620 and the second locking assembly 630 respectively assemble the assembly screws 500 on both sides of the molded case circuit breaker 300. Specifically, the second locking assembly 630 is disposed on the first bracket 610. The loading position includes a second loading position. The second locking assembly 630 is capable of attracting the assembly screw 500 at the second loading position and assembling it into the corresponding threaded hole 310. In this embodiment, the structure of the second locking component 630 is the same as that of the first locking component 620. This arrangement does not require the additional development of the second locking component 630, which helps reduce R&D costs.

[0092] Specifically, if Figure 5-7As shown, in this embodiment, the first locking assembly 620 includes an assembly control module 621, a locking module 622 and a first driving member 623. The assembly control module 621 includes a first mounting plate 6211, an auxiliary assembly assembly 6212 and a first sensor 6213. The first mounting plate 6211 is vertically slidably connected to the first bracket 610. The auxiliary assembly assembly 6212 includes a slide bar 62121, a stopper 62122, a first sleeve 62123, and a first resetting elastic member 62124. One end of the slide bar 62121 is fixedly connected to the first mounting plate 6211, and the other end extends vertically. The first sleeve 62123 is slidably mounted on the outside of the slide bar 62121. The stopper 62122 is provided at the other end of the slide bar 62121. The first resetting elastic member 62124 is disposed between the first sleeve 62123 and the stopper 62122. Sliding the first sleeve 62123 compresses the first resetting elastic member 62124. The first sensor 6213 is disposed on one side of the first mounting plate 6211. The locking module 622 includes a second mounting plate 6221, a bit assembly 6222, and a first sensing plate 6223. The second mounting plate 6221 is fixedly connected to the first sleeve 62123. The bit assembly 6222 is fixedly connected to the second mounting plate 6221 and slidably penetrates the first mounting plate 6211. That is, the second mounting plate 6221 can drive the bit assembly 6222 to move vertically relative to the first mounting plate 6211. During the movement of the second mounting plate 6221 relative to the first mounting plate 6211, the first sleeve 62123 compresses the first return elastic member 62124. The bit assembly 6222 can install the assembly screw 500 located at the first loading position into the corresponding threaded hole 310 and tighten the assembly screw 500 according to a set torque. The torque can be set according to the tightening degree of the assembly screw 500. The first sensor 6213 is signal-connected to the bit assembly 6222. The first sensing plate 6223 is disposed on the second mounting plate 6221. When the first sensing plate 6223 blocks the first sensor 6213, the bit assembly 6222 ceases operation, completing the installation of the assembly screw 500. The first sensor 6213 may, but is not limited to, a slot-type photoelectric switch. By providing the first sensor 6213 and the first sensing plate 6223, the insertion depth of the assembly screw 500 into the threaded hole 310 can be controlled, preventing the assembly screw 500 from being screwed too deeply into the threaded hole 310 and damaging the threaded hole 310, thereby improving the reliability of the assembly screw 500 assembly by the bit assembly 6222. The fixed end of the first driving member 623 is disposed on the first bracket 610. The output end of the first driving member 623 is drivingly connected to the first mounting plate 6211, for driving the first mounting plate 6211 in a vertical direction. The first driving member 623 may, but is not limited to, a stroke-adjustable pneumatic cylinder. The first locking assembly 620 realizes the automatic assembly of the combination screw 500 and has a simple structure and low cost.

[0093] Optionally, in this embodiment, two auxiliary assembly assemblies 6212 are provided, and the two auxiliary assembly assemblies 6212 are respectively arranged on both sides of the bit assembly 6222, which is conducive to improving the reliability of the movement of the second mounting plate 6221 relative to the first mounting plate 6211. Of course, in other embodiments, the number of auxiliary assembly assemblies 6212 can be other, such as one, three, etc., according to actual needs.

[0094] Preferably, continue to see Figure 6 The assembly control module 621 further includes a mounting post 6214, one end of which is connected to the first mounting plate 6211 and the other end of which extends vertically. A first sensor 6213 is mounted on the mounting post 6214, and the vertical position of the first sensor 6213 is adjustable. Optionally, in this embodiment, the first sensor 6213 is mounted on the mounting post 6214 via a first clamp 6215, that is, the first clamp 6215 is movably mounted on the mounting post 6214. When the position of the first sensor 6213 needs to be adjusted, the first clamp 6215 is released, and the first clamp 6215 is slid along the mounting post 6214 to the desired position. The first clamp 6215 then clamps the mounting post 6214. At this point, the first sensor 6213 becomes immovable, completing the position adjustment of the first sensor 6213. By setting the position of the first sensor 6213 in the vertical direction to be adjustable, the depth of the combination screw 500 screwed into the threaded hole 310 can be adjusted by adjusting the height of the first sensor 6213 in the vertical direction to adapt to different models of molded case circuit breakers 300, thereby improving the universality of the above-mentioned molded case circuit breaker combination screw automatic assembly device.

[0095] Optionally, in this embodiment, continue to refer to Figure 6 The first mounting plate 6211 is provided with an avoidance hole 62111, and the screwdriver bit assembly 6222 is slidably passed through the avoidance hole 62111. By providing the avoidance hole 62111, the screwdriver bit assembly 6222 can be avoided, thereby ensuring the reliability of the movement of the screwdriver bit assembly 6222 relative to the first mounting plate 6211.

[0096] Furthermore, if Figure 7 As shown, the bit assembly 6222 includes a handle 62221. A mounting hole 62211 is defined in the second mounting plate 6221. The handle 62221 is inserted into the mounting hole 62211 and is fixedly connected to the second mounting plate 6221. Optionally, in this embodiment, the handle 62221 is fixedly connected to the second mounting plate 6221 via a connector 6224. Specifically, one end of the connector 6224 is connected to the second mounting plate 6221, and the other end is connected to the handle 62221. The provision of the connector 6224 can improve the connection strength between the handle 62221 and the second mounting plate 6221.

[0097] Preferably, if Figure 7 and Figure 8 As shown, the bit assembly 6222 also includes a bit 62222, a second sleeve 62223, a magnetic member 62224, and a second resetting elastic member 62225. The bit 62222 is rotatable. Specifically, the bit 62222 is rotatably connected to the handle 62221. The handle 62221 is provided with a motor that can drive the bit 62222 to rotate, so that the bit 62222 can automatically screw the combination screw 500 into the threaded hole 310. One end of the bit 62222 is provided with a guide post 622221. The inner wall of the second sleeve 62223 is provided with a second slide groove 622231 extending in a vertical direction. The second sleeve 62223 is sleeved on one end of the bit 62222. The guide post 622221 is slidably connected to the second slide groove 622231. The guide post 622221 is slidably connected to the second slide groove 622231, and the second slide groove 622231 extends in the vertical direction, thereby guiding the sliding of the second sleeve 62223. The magnetic member 62224 is annular and is disposed at the end of the second sleeve 62223 not connected to the bit 62222. The magnetic member 62224 is attached to the inner wall of the second sleeve 62223, allowing the magnetic member 62224 to avoid the bit 62222 and prevent the magnetic member 62224 from obstructing the sliding of the second sleeve 62223. When the bit assembly 6222 contacts the assembly screw 500 at the first loading position, the magnetic member 62224 attracts the assembly screw 500, and then moves the assembly screw 500 to directly above the threaded hole 310. At this time, due to certain differences in height between different types of molded case circuit breakers 300, the second sleeve 62223 can move upward a distance, which is beneficial for protecting the second sleeve 62223 and the magnetic member 62224. The second reset elastic member 62225 is sleeved on the bit 62222, and the bit 62222 is provided with an abutment surface 622222. One end of the second reset elastic member 62225 abuts against the abutment surface 622222, and the other end abuts against the second sleeve 62223. By providing the second reset elastic member 62225, when the combination screw 500 is screwed into the threaded hole 310, the magnetic member 62224 can always adsorb the combination screw 500, ensuring that the combination screw 500 is always in a vertical state, making it easy to screw in, and improving the reliability of the bit assembly 6222.

[0098] Preferably, if Figure 4 and Figure 9As shown, the locking mechanism 600 further includes a material detection mechanism 624, which includes a third mounting plate 6241 and a second sensor 6242. The third mounting plate 6241 is disposed on the first bracket 610, specifically below the first locking assembly 620. The second sensor 6242 is disposed on the third mounting plate 6241 and is used to detect whether the assembly screw 500 is present on the bit assembly 6222. The second sensor 6242 may be, but is not limited to, a photoelectric switch. The second sensor 6242 is signal-connected to the feeding mechanism 400. Specifically, after the bit assembly 6222 absorbs the assembly screw 500, the first drive member 623 drives the first mounting plate 6211 to move vertically upward. This upward movement of the first mounting plate 6211 drives the bit assembly 6222 to move vertically upward. When the assembly screw 500 blocks the second sensor 6242, the second sensor 6242 can detect the presence of the assembly screw 500 on the bit assembly 6222. If the second sensor 6242 is not blocked, it indicates that the assembly screw 500 is not on the bit assembly 6222. At this time, the feeding mechanism 400 receives a no-load signal and starts feeding again. The feeding mechanism 400 can be set to repeat the feeding process a number of times. If this number of repeated feedings is exceeded, an alarm is issued and manual processing is performed. In this embodiment, the number of repeated feedings is three. In other embodiments, the number of repeated feedings can be set to another number, depending on actual needs.

[0099] Furthermore, since this embodiment also includes a second loading position and a second locking assembly 630, the material detection mechanism 624 also includes a third sensor 6243. The third sensor 6243 is disposed on the third mounting plate 6241 to detect whether the assembly screw 500 is present on the second locking assembly 630. The third sensor 6243 can be, but is not limited to, a photoelectric switch. The operating principle of the third sensor 6243 is the same as that of the second sensor 6242, and therefore, the operating process of the third sensor 6243 is not further described.

[0100] Preferably, continue to see Figure 9The material detection mechanism 624 also includes a connecting plate 6244 and a sixth driving member 6245. The connecting plate 6244 is slidably connected to the third mounting plate 6241. The fixed end of the sixth driving member 6245 is disposed on the third mounting plate 6241. The output end of the sixth driving member 6245 is drivingly connected to the connecting plate 6244 and is used to drive the connecting plate 6244 to slide. The sliding direction of the connecting plate 6244 is perpendicular to the vertical direction. The second sensor 6242 and the third sensor 6243 are both disposed on the connecting plate 6244. By providing a slidable connecting plate 6244, the positions of the second sensor 6242 and the third sensor 6243 can be adjusted according to actual needs, thereby improving the reliability of the second sensor 6242 and the third sensor 6243 in detecting the combination screw 500. The sixth driving member 6245 can optionally be, but is not limited to, a cylinder.

[0101] Optionally, in this embodiment, a second slide rail 62411 is provided on the third mounting plate 6241, and a second slider 62441 is provided on the connecting plate 6244. The second slide rail 62411 is slidably connected to the second slider 62441. The provision of the second slide rail 62411 and the second slider 62441 can improve the smoothness of sliding between the connecting plate 6244 and the third mounting plate 6241.

[0102] Preferably, continue to see Figure 9 The third mounting plate 6241 is further provided with two first buffers 62412, which are arranged opposite each other along the direction of movement of the connecting member 6224. The connecting plate 6244 is provided with a first limit block 62442, which is capable of sliding between and abutting the two first buffers 62412. The provision of the first buffers 62412 and the first limit block 62442 limits the sliding travel of the connecting member 6224. The contact between the first buffer 62412 and the first limit block 62442 is flexible, which not only limits the sliding travel of the connecting member 6224 but also protects the first limit block 62442.

[0103] Preferably, continue to see Figure 9 The connecting plate 6244 is further provided with a second limit block 62443 and a third limit block 62444. The second limit block 62443 and the third limit block 62444 can respectively abut against the first and second loading positions of the loading mechanism 400, thereby assisting the loading mechanism 400 in loading. The provision of the second limit block 62443 and the third limit block 62444 improves the reliability of the loading operation of the loading mechanism 400.

[0104] Furthermore, if Figure 10As shown, the locking mechanism 600 further includes a third slide rail 611 and a third slider 612. The third slide rail 611 is disposed on the first bracket 610 and extends vertically. The third slider 612 is slidably connected to the third slide rail 611, and the first mounting plate 6211 is fixedly connected to the third slider 612. The provision of the third slide rail 611 and the third slider 612 improves the smoothness of the sliding connection between the first mounting plate 6211 and the first bracket 610. Preferably, a second buffer 613 is provided at one end of the third slide rail 611, and the first mounting plate 6211 can abut against the second buffer 613. The provision of the second buffer 613 limits the sliding travel of the first mounting plate 6211, preventing the third slider 612 from disengaging from the third slide rail 611. The contact between the second buffer 613 and the first mounting plate 6211 is flexible, which helps protect the first mounting plate 6211. In this embodiment, the sliding connection structure between the second locking assembly 630 and the first bracket 610 is the same as the sliding connection structure between the first locking assembly 620 and the first bracket 610 described above, and therefore, details thereof will not be repeated.

[0105] For ease of understanding, the working process of the first locking component 620 is briefly introduced below:

[0106] First, the output end of the first driving member 623 descends vertically to a first preset position. At this time, the second sleeve 62223 of the bit assembly 6222 contacts the combination screw 500 at the first loading position, and the magnetic member 62224 attracts the combination screw 500.

[0107] Then, the output end of the first driving member 623 rises vertically to the second preset position, and the second sensor 6242 detects the assembly screw 500. If the second sensor 6242 detects the assembly screw 500, the output end of the first driving member 623 descends vertically to the third preset position, so that the assembly screw 500 is aligned with the threaded hole 310. During this process, the second mounting plate 6221 moves relative to the first mounting plate 6211, and the first return elastic member 62124 is in a compressed state. If the second sensor 6242 does not detect the assembly screw 500, the feeding mechanism 400 feeds again, and the first driving member 623 descends vertically to the first preset position to remove the material until the second sensor 6242 detects the assembly screw 500.

[0108] Afterwards, the bit assembly 6222 is activated, and the bit 62222 rotates to screw the combination screw 500 into the threaded hole 310. During this process, the first resetting elastic member 62124 applies pressure to the second mounting plate 6221, causing the second mounting plate 6221 to move downward in the vertical direction, driving the bit 62222 to move downward in the vertical direction, screwing the combination screw 500 into the threaded hole 310. When the first sensing piece 6223 blocks the first sensor 6213, the bit 62222 stops rotating, completing the installation of the combination screw 500.

[0109] Finally, the output end of the first driving member 623 returns to the initial position.

[0110] Furthermore, if Figure 11 As shown, the feeding mechanism 400 includes a feeding assembly 410 and a dividing assembly 420. The feeding assembly 410 is capable of transporting the assembly screw 500 to a preset position. The dividing assembly 420 includes a second bracket 421, a first dividing plate 423, and a second driving member 422. The second bracket 421 is disposed on the workbench 100 and is used to support the second driving member 422 and the first dividing plate 423. The first dividing plate 423 is slidably connected to the second bracket 421. The preset positions include a first position 4231, which is disposed on the first dividing plate 423. The fixed end of the second driving member 422 is arranged on the second bracket 421, and the output end of the second driving member 422 is driven and connected to the first dividing plate 423. The second driving member 422 can drive the first dividing plate 423 to move, so as to move the combination screw 500 at the first position 4231 to the loading position. In this embodiment, the first dividing plate 423 can move the combination screw 500 at the first position 4231 to the first loading position. The second driving member 422 is optional but not limited to a cylinder. Furthermore, in this embodiment, the dividing assembly 420 also includes a second dividing plate 424 and a seventh driving member 425. The second dividing plate 424 is slidably connected to the second bracket 421, and the preset position also includes a second position, which is arranged on the second dividing plate 424. The seventh drive member 425 has its fixed end mounted on the second bracket 421. Its output end is drivingly connected to the second distributor plate 424. The seventh drive member 425 is capable of driving the second distributor plate 424 to move the assembly screw 500 at the second position to the second loading position. The seventh drive member 425 can optionally be, but is not limited to, a pneumatic cylinder. The aforementioned loading mechanism 400 has a simple structure, low cost, and is easy to control.

[0111] Optionally, in this embodiment, the feeding mechanism 400 is a vibrating disc screw loader, which can deliver the assembly screws 500 to the first position 4231 and the second position, respectively. The vibrating disc screw loader can continuously, stably, and accurately provide the assembly screws 500. Compared with manual feeding, it greatly reduces the time wasted by manual material removal and improves production efficiency. In other embodiments, the feeding mechanism 400 can also be configured in other ways, according to actual needs.

[0112] Preferably, continue to see Figure 11 A fourth sensor 411 is provided on the feeding mechanism 400, located directly above the first position 4231. A fifth sensor 412 is provided on the feeding mechanism 400, located directly above the second position. The fourth sensor 411 is used to detect the presence of material at the first position 4231, and the fifth sensor 412 is used to detect the presence of material at the second position. The provision of the fourth sensor 411 and the fifth sensor 412 ensures the reliability of the feeding operation of the feeding mechanism 400. The fourth sensor 411 and the fifth sensor 412 can be alternatively, but not limited to, the first sensor 6213.

[0113] It is worth noting that, in this embodiment, the first dividing plate 423 can abut against the second limiting block 62443 , and the second dividing plate 424 can abut against the third limiting block 62444 , so as to ensure the accuracy of material loading of the first dividing plate 423 and the second dividing plate 424 .

[0114] Preferably, if Figure 12 As shown, in this embodiment, the second bracket 421 is provided with a fourth slide rail 4211 and a fourth slider 4212. The fourth slider 4212 is slidably connected to the fourth slide rail 4211, and the first dividing plate 423 is fixedly connected to the fourth slider 4212.

The fifth slider 4214 is slidably connected to the fifth slide rail 4213, and the second dividing plate 424 is fixedly connected to the fifth slider 4214. By providing the fourth slide rail 4211 and the fourth slider 4212, the smoothness of the movement of the first dividing plate 423 can be improved. By providing the fifth slide rail 4213 and the fifth slider 4214, the smoothness of the movement of the second dividing plate 424 can be improved. In other embodiments, the sliding connection structure between the first dividing plate 423, the second dividing plate 424 and the second bracket 421 can also be set to other structures, which can be set according to actual needs.

[0115] Furthermore, if Figure 13As shown, the assembly inspection module includes a third bracket 710 and a CCD visual inspection module 720. The third bracket 710 is set on the workbench 100 and is used to support the CCD visual inspection module 720. The CCD visual inspection module 720 can determine whether the assembled molded case circuit breaker 300 is qualified, and transmit the unqualified signal to the defective product transfer mechanism 800. The defective product transfer mechanism 800 moves the corresponding molded case circuit breaker 300 to the defective product station 810 according to the unqualified signal. Since the CCD visual inspection module 720 is a prior art, its specific structure is not described again. By setting the CCD visual inspection module 720, defective products can be intelligently identified, and defective products can be prevented from flowing into the next process, thereby improving the yield of the molded case circuit breaker 300.

[0116] Furthermore, if Figure 14 As shown, in this embodiment, the defective product transfer mechanism 800 includes a defective product station 810, a pusher assembly, and a limit assembly. The defective product station 810 is arranged on one side of the conveyor line 200. The limit assembly can limit the movement of defective products, and the pusher assembly can push the defective products to the defective product station 810. The pusher assembly includes a fourth bracket 820, an eighth driving member 830, and a pusher plate 840. The fourth bracket 820 is arranged on the workbench 100, the fixed end of the eighth driving member 830 is arranged on the fourth bracket 820, and the output end of the eighth driving member 830 is connected to the pusher plate 840 for driving the pusher plate 840 to move. The pusher plate 840 can push the defective products on the conveyor line 200 into the defective product station 810. Specifically, the defective product station 810 is provided with an opening 811, which is opposite to the pusher plate 840. The pusher plate 840 pushes the defective products into the defective product station 810 through the opening 811. The eighth driving member 830 may be, but is not limited to, a pneumatic cylinder. The limiting assembly includes a fifth bracket 850, a ninth driving member 860, and a material stop plate 870. The fifth bracket 850 is disposed on the workbench 100. The fixed end of the ninth driving member 860 is disposed on the fifth bracket 850. The output end of the ninth driving member 860 is drivingly connected to the material stop plate 870. The ninth driving member 860 can drive the material stop plate 870 to abut against the molded case circuit breaker 300 to limit the conveyance of the molded case circuit breaker 300. The ninth driving member 860 may be, but is not limited to, a pneumatic cylinder.

[0117] Preferably, the defective product station 810 is further provided with a tenth driving member 812. The fixed end of the tenth driving member 812 is disposed on one side of the defective product station 810. The output end of the tenth driving member 812 can abut against defective products and push the defective products along the extension direction of the defective product station 810 to prevent the defective products from blocking the opening 811. This improves the reliability of the pusher assembly and increases the capacity of the defective product station 810 for holding defective products. The tenth driving member 812 can optionally be, but is not limited to, a cylinder.

[0118] To facilitate understanding, the working process of the defective product transfer mechanism 800 is briefly introduced below:

[0119] First, according to the unqualified result transmitted by the assembly inspection mechanism 700, the ninth driving member 860 drives the blocking plate 870 to block the defective product;

[0120] Then, the eighth driving member 830 is activated to drive the push plate 840 to push the defective products into the defective product station 810 at the opening 811 ;

[0121] Finally, the tenth driving member 812 is activated to push the defective products away from the outlet 811 .

[0122] Furthermore, if Figure 1 、 Figure 15 and Figure 16 As shown, the aforementioned automatic assembly device for molded case circuit breaker assembly screws further includes a transverse movement mechanism 900, which is disposed on a workbench 100. The assembly station is disposed on the transverse movement mechanism 900. The transverse movement mechanism 900 is capable of moving the molded case circuit breaker 300 multiple times by a set distance, allowing the locking mechanism 600 to sequentially complete the assembly of multiple assembly screws 500. In this embodiment, the transverse movement mechanism 900 is capable of moving the molded case circuit breaker 300 three times by a set distance, with the locking mechanism 600 completing the assembly of two assembly screws 500 with each movement. By providing the transverse movement mechanism 900, micro-displacements of the molded case circuit breaker 300 can be controlled, allowing the threaded hole 310 to be assembled to be directly below the locking mechanism 600, facilitating precise assembly of the locking mechanism 600.

[0123] Further, see Figure 15 and Figure 16The transverse movement mechanism 900 includes a linear module 910 and a lifting module 920. The linear module 910 is disposed on the workbench 100, and the lifting module 920 is disposed on the linear module 910. The linear module 910 can drive the lifting module 920 to move along the conveying direction of the conveyor line 200 according to a set distance. The lifting module 920 can lift the molded case circuit breaker 300 to be off the conveyor line 200 to facilitate the assembly of the combination screws 500. In this embodiment, the lifting module 920 includes a base plate 921, a third driving member 922, an oblique plug-in 923, and two lifting assemblies 924. The linear module 910 is connected to the base plate 921 in a driving manner, thereby achieving the purpose of driving the entire lifting module 920 to move. The fixed end of the third driving member 922 is arranged on the bottom plate 921. The output end of the third driving member 922 is drivingly connected to the oblique plug-in 923, and is used to drive the oblique plug-in 923 to move along the conveying direction of the conveyor line 200. The oblique plug-in 923 includes an inclined surface 9231, and the inclined surface 9231 extends along the conveying direction of the conveyor line 200. Two lifting assemblies 924 are respectively arranged on both sides of the bottom plate 921. The lifting assembly 924 includes a first slide rail 9241, a first slider 9242, a follower 9243, a support block 9244 and a stopper 9245, wherein the first slide rail 9241 is arranged on the bottom plate 921 and extends in the vertical direction. The first slider 9242 is slidably connected to the first slide rail 9241. The follower 9243 is arranged at the bottom of the first slider 9242. The inclined surface 9231 can be inserted into the bottom of the follower 9243. The end of the surface 9231 close to the follower 9243 is lower than the end away from the follower 9243. When the inclined surface 9231 is inserted into the bottom of the follower 9243 and moves along the conveying direction of the conveyor line 200, it pushes the follower 9243 to move upward in the vertical direction, and then pushes the first slider 9242 to move upward in the vertical direction. The support block 9244 is arranged above the first slider 9242, and the stop block 9245 is arranged on the support block 9244. The stop block 9245 can abut against the molded case circuit breaker 300. Specifically, the conveyor line 200 can convey the molded case circuit breaker 300 to the two support blocks 9244. The space enclosed by the two support blocks 9244 is the assembly station. Then the third driving member 922 is started, and the output end of the third driving member 922 drives the oblique plug-in 923 to move, so that the first slider 9242 moves upward in the vertical direction, and then the support block 9244 lifts the molded case circuit breaker 300 away from the conveyor line 200. At this time, the movement of the conveyor line 200 will not affect the position of the molded case circuit breaker 300, thereby improving the reliability of the assembly work of the combination screw 500.

[0124] Preferably, the first slide rail 9241 is provided with a first slide groove 92411 extending along the direction of installation. The end of the follower 9243 not in contact with the inclined surface 9231 is slidably connected to the first slide groove 92411 and can be engaged with the groove wall of the first slide groove 92411. This arrangement enables the first slide groove 92411 to guide the sliding of the first slider 9242 and limit the sliding stroke of the first slider 9242. Optionally, in this embodiment, the follower 9243 is a cam follower. The friction between the cam follower and the inclined surface 9231 is rolling friction, which has a low friction force and is conducive to protecting the inclined surface 9231.

[0125] Further, see Figure 15 and Figure 16 Lifting assembly 924 further includes a sixth sensor 925, which is disposed on one of the two support blocks 9244. This sensor 925 is capable of detecting whether a molded case circuit breaker 300 is present on support block 9244. Third driver 922 operates based on the detection result of sixth sensor 925, i.e., when sixth sensor 925 detects a molded case circuit breaker 300 on support block 9244, third driver 922 is activated. Sixth sensor 925 may be, but is not limited to, a photoelectric switch. The provision of sixth sensor 925 ensures that a molded case circuit breaker 300 is present on support block 9244 when lifting module 920 is lifted, thereby enhancing the intelligence of the aforementioned automatic assembly device for molded case circuit breaker combination screws.

[0126] Preferably, continue to see Figure 15 and Figure 16 Lifting assembly 924 further includes a second clamp 926, which is disposed on one of the two support blocks 9244. Second clamp 926 includes a telescopic head. When molded case circuit breaker 300 is placed onto support block 9244, the telescopic head of second clamp 926 extends, clamping molded case circuit breaker 300 between the telescopic head and the other support block 9244. Second clamp 926 may be, but is not limited to, a cylinder. The provision of second clamp 926 improves the securing effect on molded case circuit breaker 300 and reduces the risk of the molded case circuit breaker 300 falling during the lifting process.

[0127] Further, if Figure 17As shown, in this embodiment, the linear module 910 includes a fourth mounting plate 911, an eleventh driving member 912, a lead screw 913, and a nut 914.

By driving the base plate 921 to move via the lead screw 913 and nut 914 mechanism, the accuracy of the movement of the lifting module 920 can be improved, and the precise positioning of the threaded hole 310 and the locking mechanism 600 can be achieved. The structure is simple, the friction resistance is low, and the manufacturing cost is low.

[0128] Preferably, continue to see Figure 17 A sixth slide rail 915 is provided on the fourth mounting plate 911. The sixth slide rail 915 extends along the conveying direction of the conveyor line 200. The sixth slider 916 is slidably connected to the sixth slide rail 915.

[0131] For ease of understanding, the working process of the transverse movement mechanism 900 is briefly introduced:

[0132] First, the conveyor line 200 conveys the molded case circuit breaker 300 to the support block 9244. The seventh sensor 917 detects the molded case circuit breaker 300, the second clamp 926 extends to clamp the molded case circuit breaker 300, and the third driving member 922 is activated to lift the molded case circuit breaker 300.

[0133] Then, the linear module 910 moves the molded case circuit breaker 300 for the first time according to the set distance, and the locking mechanism 600 completes the assembly of the two combination screws 500; the linear module 910 moves the molded case circuit breaker 300 for the second time according to the set distance, and the locking mechanism 600 completes the assembly of the two combination screws 500; the linear module 910 moves the molded case circuit breaker 300 for the third time according to the set distance, and the locking mechanism 600 completes the assembly of the two combination screws 500, and the assembly is completed;

[0134] Finally, the third driving member 922 is started to put the molded case circuit breaker 300 back onto the conveyor line 200 , and the conveyor line 200 continues to convey it.

[0135] Further, if Figure 1 and Figure 18 As shown, the above-mentioned automatic assembly device for molded case circuit breakers with combined screws further includes a retaining mechanism 1000. The retaining mechanism 1000 is disposed on the workbench 100 and is located between the input end of the conveyor line 200 and the assembly station. The retaining mechanism 1000 can limit the movement of the molded case circuit breakers 300 so that a single molded case circuit breaker 300 can be moved to the assembly station. By providing the retaining mechanism 1000, even if multiple molded case circuit breakers 300 are conveyed at once at the input end of the conveyor line 200, the sequential assembly of the molded case circuit breakers 300 can be ensured, thereby preventing multiple molded case circuit breakers 300 from piling up at the assembly station and affecting the assembly work.

[0136] Specifically, see Figure 18In this embodiment, the blocking mechanism 1000 includes a first blocking assembly 1100 and a second blocking assembly 1200. The first blocking assembly 1100 is closer to the assembly station than the second blocking assembly 1200. The first blocking assembly 1100 and the second blocking assembly 1200 are used to respectively limit the conveyance of two adjacent molded case circuit breakers 300, so that a single molded case circuit breaker 300 can be moved to the assembly station. The first blocking assembly 1100 includes a fourth driving member 1110 and a first blocking member 1120. The fourth driving member 1110 can drive the first blocking member 1120 to extend and retract. When the first blocking member 1120 is extended, the molded case circuit breaker 300 can abut against the first blocking member 1120 and stop moving. When the blocking member retracts, the molded case circuit breaker 300 can be conveyed normally. The fourth driving member 1110 is optionally, but not limited to, a cylinder. In this embodiment, the fourth driving member 1110 is disposed on the side wall of the conveyor line 200, and two fourth driving members 1110 are provided, with the two fourth driving members 1110 disposed on both sides of the conveyor line 200. The second material blocking assembly 1200 includes a fifth driving member 1210 and a second material blocking member 1220. The fifth driving member 1210 can drive the second material blocking member 1220 to move in a vertical direction and be inserted into the molded case circuit breaker 300. Specifically, it can be inserted into the threaded hole 310 of the molded case circuit breaker 300 to stop the molded case circuit breaker 300 from moving. The fifth driving member 1210 is optionally, but not limited to, a cylinder. In this embodiment, the second material blocking assembly 1200 also includes a sixth bracket 1230. The sixth bracket 1230 is disposed on the workbench 100, and the fifth driving member 1210 is disposed on the sixth bracket 1230. The first stopper 1120 and the second stopper 1220 can respectively limit the conveyance of two adjacent molded case circuit breakers 300. When the first stopper 1120 is in a retracted state, the second stopper 1220 is inserted into the molded case circuit breaker 300, that is, only one molded case circuit breaker 300 is allowed to flow into the assembly station at a time.

[0137] Preferably, the second material stop assembly 1200 also includes an eighth sensor 1240, which is arranged on the sixth bracket 1230. The eighth sensor 1240 can detect whether there is a molded case circuit breaker 300 under the second material stop assembly 1200 to ensure that the second material stop member 1220 can be accurately inserted into the molded case circuit breaker 300, thereby improving the reliability of the second material stop assembly 1200.

[0138] For ease of understanding, the working process of the above-mentioned blocking and dismantling mechanism 1000 is briefly introduced:

[0139] First, the fourth driving member 1110 drives the first stopper 1120 to extend. When the eighth sensor 1240 detects the molded case circuit breaker 300, the fifth driving member 1210 drives the second stopper 1220 to insert into the molded case circuit breaker 300.

[0140] Then, the fourth driving member 1110 drives the first stopper 1120 to retract. At this time, the second stopper 1220 remains inserted into the molded case circuit breaker 300, so that the molded case circuit breaker 300 abutting against the first stopper 1120 enters the assembly station under the conveyor line 200 to wait for assembly of the assembly screw 500.

[0141] Finally, the fourth driving member 1110 drives the first blocking member 1120 to extend, and the fifth driving member 1210 drives the second blocking member 1220 to disengage from the molded case circuit breaker 300, so that the molded case circuit breaker 300 abuts against the first blocking member 1120 on the conveyor line 200 of the conveyor line 200, and the fifth driving member 1210 drives the second blocking member 1220 to insert into the molded case circuit breaker 300 adjacent to the molded case circuit breaker 300.

If there is no material at the first position 4231 or the second position, the loading component 410 will load material again until there is material at both the first position 4231 and the second position.

[0158] S220, the conveying end of the second driving member 422 drives the first dividing plate 423 to convey the combination screw 500 at the first position 4231 to the first loading position, and the output end of the seventh driving member 425 drives the second dividing plate 424 to convey the combination screw 500 at the second position to the second loading position.
